摘　　要：目的:研究茶梅Camellia sasanqua花挥发油的化学成分。方法:采用水蒸气蒸馏法,得到茶梅花挥发油,利用气相色谱-质谱联用技术进行化学成分分析。结果:共分离出19个峰,用面积归一化法测定其相对质量分数,并鉴定出全部茶梅花挥发油中19种化学成分。结论:茶梅花挥发油化学成分包含有机酸、烷烃、萜类及其衍生物,萜类主要为倍半萜,其衍生物则主要为酮类,含量最高的是十六烷酸(25.154%),其次是正二十七烷(22.310%),正二十五烷(19.612%),正二十九烷(9.673%)和丁香酚(4.049%)。Objective： To study the chemical constituents of the volatile oil from the flowers of Camellia sasanqua. Method： The volatile oil was extracted by steam distillation and was identified by GC-MS. The composition of the volatile oil was determined according to peak area normalization method. Result： Ninteen components were separated and all compounds were identified from the flowers of C. sasanqua. Conclusion： Chemical constituents of the volatile oil from the flowers of C. sasanqua include organic acids, alkane, terpenoids and its derivatives. The main constituents were hexadecanoic acid （25. 154% ）, heptacosane （22. 310% ）, pentacosane （ 19. 612% ） , nonacosane （9. 673% ） and eugenol （4. 049% ）.
